There have been times I've told my children they could not have something. The response was a natural response from a child, as they don't understand the withholding of something by a parent whom they feel loves them so much they would withhold nothing. And the immediate response was not manipulative, nor coercive ...my child simply felt, for that ever so brief moment, "You don't love me!" The moment was ever so short, because I immediately hugged my child, and then the truth outweighed the counter emotion.
